I went to bid on an eBay item from Eric Jackson (an item for a few dollars) and find that I am blocked from both bidding and contacting him. I have no idea why since I have never had any transactions with him.
There must have been something in the past that caused someone in my office to block your account. Give us a call tomorrow 610-926-6200 or send me an email and I'll get it unblocked. I'll need your eBay user name and email address.
